As he has done so many times, Republican Donald Trump decided to start his day with a disgusting attack against someone on Twitter. This time the target of his awfulness was New York Democrat, Senator Kirsten Gillibrand.

Lightweight Senator Kirsten Gillibrand, a total flunky for Chuck Schumer and someone who would come to my office “begging” for campaign contributions not so long ago (and would do anything for them), is now in the ring fighting against Trump. Very disloyal to Bill & Crooked-USED!

The disgustingly sexist tweet did not go unnoticed by the Democrat and fierce champion against sexual assault. Gillibrand fired back at the president, calling him unfit for the presidency and pointing out the “shame” he has brought to the White House.

You cannot silence me or the millions of women who have gotten off the sidelines to speak out about the unfitness and shame you have brought to the Oval Office. https://t.co/UbQZqubXZv

Joining her fellow Democrat in rebutting Donald Trump was Massachusetts senator and frequent target of the president’s attacks, Elizabeth Warren. The Democrat scolded Trump for “trying to bully, intimidate and slut-shame” Kirsten Gillibrand and asked if he knew who he’s “picking a fight with”.

There is little doubt Republican Donald Trump is feeling the pressure mount over his accusers after high-profile legislators have resigned recently. Longtime Democratic Rep. John Conyers announced his retirement last week following numerous allegations of sexual misconduct. He was soon followed by Minnesota Senator Al Franken, who announced he would be resigning his seat soon while asking why the president was not also doing the same.

Gillibrand joined her fellow Senators Bernie Sanders, Jeff Merkley, Ron Wydenand Cory Booker in calling for Donald Trump to step down. The White House has officially stated that all of the president’s accusers are liars.

Donald Trump will continue issuing his disgraceful attacks against anyone who crosses his path in even the slightest way. And, like we see today, he should probably stay away from the people that will persist in fighting back his overt sexism.
